You can manually create a group from Manager. See User and Group APIs (archived) for information on creating groups programmatically.
To create a group:
The group name may contain UTF-8 alphanumeric characters, space, and dash "-" only. Other punctuation characters, such as !"#$%&'()*+,.:;<=>?@[]^_`{|}~, are not supported. |
The group is added to the Org you are currently logged in to. Groups cannot be shared across Orgs.
